tivator beam and operated by the spokes of the wheels of the cultivator.

A further object is to provide a seeder comprising a receptacle having a vertically disposed shaft therein, said shaft being 0perated through gearing, which gearing is rotated by horizontally ydisposed arms coopera-ting with the spokes of the wheel of the cultivator. Also to provide a horizontally disposed star shaped scatterer, into pockets of which the seed pass from the receptacle, Said pockets having one of their sides open whereby as the star shaped scattered rotates in one direction, the seed will be thrown out `of the pockets, and when rotated in the other direction will be retained within the pockets.

A further object is to provide a shield whereby seed will be prevented from being deposited back of the cultivated ground;

lVith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

ln the drawings Figure 1 is a top plan view of the seeder, showing the same applied to a cultivator, of the wheeled type.

Figure 2 is a vertical longitudinal sectional view taken on line 2-2 of Figure 1.

Figure 3 is a top plan view of the star shaped scatterer.

- Figure 6 is a horizontal sectional View taken on line 6 6 of Figure 5.

Figure 7 is a detail perspective view of a vportion ofthe regulating slide for regulating the feeding of seed from the receptacle I to the scatterer.

Referring to the' drawings, the numeral 1 designates a conventional form of wheeled cultivator and 2 the beam thereof. Thel cultivator is supportedon wheels 3 of the conventional type, which wheels rotate in Vthe direction of the arrow a, as the cultivator `moves over the ground during acultivating operation.V Detachably secured to the beam 2 by means of a U-bolt t is a seed receptacle 5, whichy receptacle is vertically disposed,

V*and is provided with a hinged cover 6 whereby access' may be hadto the interior of the receptacle 5 for placing seed therein. 'EX- tending vertically through the receptacle 5 and having bearings in the upper and lower ends thereof is a shaft 7, to the lower end of which is secured a star shaped scatterer 8,

which scatterer when the shaft is rotated rotates in the direction of the arrow b. The scatterer 8 is provided with a plurality of pockets 9, which pockets are opened as at 10. It will be seen that as the scatterer 8 is rotated in the direction of the arrow b that he .centrifugal force will cause the seed which drop into the pockets 9 through the aperture 11 in the bottom of the receptacle 5, to be forced outwardly from the pockets 9 through the open ends 10 of said pockets, thereby thoroughly scattering the seed during the cultivating operation. However upon a rearward movement of the cultivatoi, the scatterer 8 will be reversely rotated and on account of the angularly disposed walls 12 of the scatterer, said seed within the pockets 9 will be prevented from leaving said pockets. The feeding of the seed from'the receptacle 5 to the pockets 9 of the scatterer 8 may be controlled in any suitable manner, however, for purposes of illustration an apertured slide 13 is disposed in the bottom of the receptacle 5,

Vwhich slide may be adjusted in various poposed shaft 22. The vertical-ly disposed shaft 22 is rotatably mountedin bearings of brackets 23, which bracketsl brace the parts and vmaintain the gears .20,andv2l in mesh. Secured tothe upper end of the shaft y22I isa sleeve 24, which sleeveis provided 'i with a plurality of horizontally disposed karms 25, which extend through the wheel 3., andare engaged byk the spokes 26 when v tlie.wheel Bis rotated. It will be seen that as the wheel 3 rotates in the direction of the arrow a that the large gear 2l willbe rotated and as the gear 21V meshes with the small :gear 20 the shaft 7 will also rotate, land in turn rotate the scatterer 8. By providing the gear 20,'which is of `smaller di ameter than the vgear 2l, it will be seen that the shaftand scatterer will. be revolved at -a rapid speed thereby obtaining sufficient speed for the scatterer to thoroughly scatterer the seed.V

FromV-the above it-will be'seein'that aV seeder is provided which may be easily and quickly attached to a conventional form of cultivator.V I v v The invention having been set forth what is claimed as new anduseful is The combination with a seeder hopper, of a scatterer carried`V by a. vertical shaft and disposed below and in engagement with the 1 wheel cultivator so constructed that the same maybe operated by thewheelf ofthe lower side of the hopper, said scatterer comprising a star shaped memberhaving a plurality of points, radially disposed vertical ribs on said member. emerging, from .theY

center and terminating at the apices of the angles 'between the points, recesses between said ribs and extending into said points, a rib extending romnthe end of said first .named ribs to the pointsrof the star shapedVv member respectively, whereby a, the recesses -orin pockets, bounded onnone side by said last'm'entioned ribs and open'on the other side, and whereby during'the rotation ofthe -star shaped member in one direction seed will lbe scattered, and upon rotationof the star shaped member in the other direction` the seed will be prevented from being scattered.

In ytestimony whereof I hereunto aix vmy signature.
